(1) and its methyl ether (2), were isolated from an Australian marine sponge Dysidea dendyi, together with the known minor metabolites methyl ethers of spongiadioxins A (4) and B (6) and polybrominated diphenyl ethers (7-9). The structures of the new compounds were established by 1D and 2D NMR spectroscopy and confirmed by synthesis of 2 from diphenyl ether 9. All isolated compounds inhibited the cell
从澳大利亚海洋海绵Dysidea dendyi中分离出两种新的次要三溴二苯并二恶英,海绵二恶英C(1)及其甲基醚(2),以及海绵二恶英A(4)和B(6的已知的次要代谢物甲基醚)。 )和多溴二苯醚(7-9)。新化合物的结构通过1D和2D NMR光谱确定,并通过从二苯醚9合成2证实。所有分离出的化合物均抑制了受精海胆卵的细胞分裂。
